5 Reasons Your Furnace Is Blowing Cold Air

We expect our furnaces to keep us warm when the temperatures drop. However, furnaces are like any other appliance and can have issues. If your furnace is blowing out cold air, here are some reasons why and how to fix them. You may require a furnace repair.

1. A Malfunctioning Limit Switch

The limit switch controls the amount of heat through the heating system. When this switch malfunctions, it will cause the furnace to blow cold air.

You need to replace the switch if it is not working properly. It is recommended that you get experienced HVAC contractors to help you with furnace repair.

2. The Blower Motor Is Faulty

Another reason why a furnace might blow cold air is due to a faulty blower motor. To repair this problem, a technician needs to remove the blower motor from the furnace. Then, they may need to clean the fan blades and the housing. Next, they’ll need to check the motor’s windings using an ohmmeter. If the technician gets a good reading, they’ll reinstall the motor. However, if they receive a bad reading from the ohmmeter, you will need a new motor installed.

3. The Thermostat Is Malfunctioning

If the thermostat is malfunctioning, it will cause the heating system to blow cold air. To fix this issue, you need to replace the thermostat. Make sure to contact our team to help you buy one compatible with your current furnace. At Climate Control Company, we offer various services, including HVAC repair in Glenwood Springs, CO.

4. The Filter Needs Cleaning

Additionally, make sure that you use only quality filters for your furnace unit. Call Climate Control Company for your furnace repairs today.
